CORROSIONPROOF BATTERY TERMINAL Filed Dec. 20, 1932 By @Mmm flllorney Patented May 1, 1934 TTE PATENT OFFICE 1 Claim.

This invention relates to a battery terminal, the general object of the invention being to make the terminal corrosion-proof and to provide means whereby a conductor can be easily and quickly connected to a battery post or released therefrom.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure l is a fragmentary elevation showing the invention in use on a battery.

Fig. 2 is a sectional view through the device.

Fig. 3 is a top plan view of the member which is connected to the conductor.

Fig. 4 is a top plan View of the member which is connected to the post.

Fig. 5 is an elevation of portion of a battery showing the socket part formed in the battery post, such post being shown in section.

In this drawing, the letter A indicates a member which is provided with a tubular part 1 for receiving the stripped end of a conductor C and a part 2 which is formed with a substantially semispherical part 3 which depends therefrom. These parts 2 and 3 are formed with the vertically arranged hole 4 for receiving the shank of the bolt 5 with the head of the bolt resting upon the upper face of the part 2, and as will be seen, this part 2 is offset downwardly from the part 1.

A member B is formed with a clamp or ring 6 for engaging the post of the battery X and said member B is formed with a substantially semispherical socket '7 for receiving the part 3. Below the socket 7 a nut 8 is embedded in the member B for receiving the threaded end of the bolt and a recess 9 connects the bottom of the socket '7 with the space occupied by the nut so that grease placed in the socket will find its way to the bore of the nut.

A gasket 10 is placed between the lower face of the part 2 and the upper face of the member B as shown to make a tight joint between the parts when the bolt is threaded into the nut.

Instead of providing the member B with the clamping part 6, I may form the socket '7' in the post :r of the battery and also place the nut 8' in the post below the socket 7 as shown in Fig. 5.

5 The members A and B are preferably formed of lead and the bolt is preferably covered with lead and before the parts are connected together by the bolt, grease should be placed in the socket and the bolt is also given a coat of grease.

Thus I have provided a battery terminal which. can be easily and quickly assembled and disassembled and one which will not corrode.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

Having thus described my invention, what I claim as new is:

A battery terminal comprising a member connected with the battery and having a semi-spherical socket in its upper end having its large end opening out through the upper face of the member, a nut embedded in the member below the socket and above the lower end of the member and said member having a recess therein for placing the bottom of the socket in communication with the bore of the nut, a second member connected to a conductor and having a semi-spherical projection depending therefrom for fitting in the socket and a bolt passing through the second member, the projection and the recess and engaging the nut, said projection being of less diameter than the lower face of the second member to provide a shoulder which surrounds the upper end of the projection and the upper end of the socket being of less diameter than the upper face of the first member to provide a second shoulder and a gasket located between the shoulders.
